TRACK-DRILLING MACHINE.

Application filed June 15, 1925., Serial in. 37,397.

bling them to clamp against the rail at abars, by adjusting thejoint having splice clamping arrangement to the rail so point of the drill may be seen when working working as drill-' has for an object to imby enathat the the machine is in operation, by providing a gage for locating the top of the rail and by arrangement of parts as scribed in the following drill point from marks on the construction and more fully despecification and shown in. the accompanying drawings, in

This invention is a continuation an improvement upon rail end drilling of and the invention disclosed in my co-pending application, Serial filed August 11, 192 i.

- In the application referred to, the machine is. arranged to drill the web of the rail with the splice barsremoved. In practice it is often necessary to drill the rail with the splice bars in place and for this purpose, in the present application, I have" arran ged the clamping memberopposite the drill to engage the the same side of with the object of rail by a plurality of stages; one stage'is effective when the clamping inemp another member web of the rail. The lockthe rail adjustably positioned on its locating it, under normal conditions, so that the oint of the drill can be seen as it enters the rail and at the same time enabling it to be located close tc the vertical. line of the drill when drilling; a stub ended all class to the rail end. According to general practice the rail is marked for drilling purposes by a chalk mark across the top of the rail and in the present construction I have provided a gaging system whereby the drill point may be correctly located from these chalk marks on the rail head without locating the centre of the drill hole on the web of the rail. In the present invention the operating levers are all arranged on the drill side of the rail and are readily accessible from the point where the drill is manipulated.

Referring to the drawings, 11 is the track rail which at the joints is provided with splice bars ,12-12- as shown in Fig. 1. The machine rolls along the rail on rollers 13-13 which support the frame members 14 and 15. The machine is substantially balanced on these rollers having the gasoline motor onone side of the rail and the drilling mechanism on the opposite side. The frame member 15 through the pedestal 16 supports the motor 17 having a magneto 18 and fly wheel 19 mounted on shaft 20 and through a train of gears in the housing 21, 22, 23 and 24 drives the drill spindle 25 opposite the web of the rail. This spindle is positioned by the adjustable foot 26 resting on the ties and is fed by the hand wheel 27 and the controlling lever 28. A rest 29 is provided. for supporting the machine in combination with 26 when it is ofi the track. For this purpose the rest 29 may be placed in the vertical position as shown in Fig. 3 and when not in use, may be turned to the horizontal position as in Fig. 1 so as to clear the rail when the machine is removed from the track. Handles 303O are provided for lifting the machine ofl the track and a pipe rail 32 is provided whereby the machine may be conveniently rolled along the track. Vertical screws 3131 are arranged to suport the machine on the top of the rail close to the line of the drill spindle and independently of the rollers 13.

The machine is locked to the rail when the drill is in operation by the handle 33 which is latched by the detent 34 to quadrant 35. This handle is secured on shaft 36 placed parallel with the rail and arranged to rotate in bearings IQ- 12. The locking mechanism 37 is clamped to this shaft and carries the ball ended screw 38 which is locked i'n position 37 by the wheel 39. The ball is in operation.

chine reaches the stud end of a rail with no 38 may be arranged to engage the shoulder of the splice bar 12 as indicated in Fig. 1, or it. may be arranged to engage under the head of the rail and holds the machine in place and prevents it from rising on the rail. Two mechanisms 37 and 37 are providedon this shaft spaced on either side of the line of the drill spindle whereby the machineis rigidly held where the drill engages the rail; he mechanism 37' is splined on shaft 36, the stud 40 engaging the spline so that this mechanism can slide on the shaft and can be located away from the drill spindleso that the latter may be inspected While it However, when the maabutting rail to rest upon, it is then neces sary to move this mechanism as close as possible to the centre of the machine so that it is in position to engage the rail.

The machine is held in: position against the thrust from the drill by a clamping device which engages the web of: the rail opposite the drill. This device is shown in Figs. 4:, 5 and 6 and comprises the quadrant 51 pivoted on'a shaft 52 and having a forked end at directly opposite the drill with enlar ed wings 5 1. Thisquadrant is latched in the engaging position against the rail by pin 57 entering aperture 55 audit is latched in the engaging position against the splice bar by the'pin 57 engaging the-end of slot 56 as indicated'in Fig. 6. The pin 57 is controlled by lever 59 on the end of shaft 60 l which rotates'in hearings 61 and 62 and is operated by handle 63. A spring 58, Fig.2 engages an arm depending from 60 which tends to hold pin 57 in engagement with 51-.

When the machine is brought to a drilling location, the handle 72 is raised which, though lever 71 is connected with shaft. 52 and thereby the quadrant islowered until'it engages the web of the rail when pin. 57 is automatically forced into the aperture 55 andthe quadrant is thereby latched in position untilhandle 63'is raised withdrawing pin 57' and permitting quadrant 51 to be raised by the action of coil spring 73 on shaft 52 or by the counterweight of handle 72 itself. When the machine is located op posite a splice bar, the handle 72 is raised as before until it is stopped by the quadrant engaging the splice bar. In this position pin 57 enters slot 56-and latches the quadrant in position until released .byhandle 63 as has been. described. It will be n'oted'that due to the action of spring 58, pin 57. is normally biased'to latch the quadrant andif an aperture were provided at 56 similar to the aperture at 55 the pin would latch the quad rant so that it could-not bemoved to its extreme position. The latching position 56' is therefore formed in a slot providing a free movement of the quadranti towards its extreme position. This is a matter of consid erable importancein handling the machine as usually the operator has only one hand available for operating handles 63 and 72.

The use of the shaft. 60 brings these handles close together and locates them conveniently machine by the rod 81 secured in lug 82 on the frame and: carrying. the index fingers 83 and 8 1 projecting over and close to the rail headr These fingers may be spaced by the graduated scale as indicated at 85. If the machine is rolled along the rail as in Fig. 7

until.v finger 84 registers with line a then the drill will'be in position to drill. the rail at a. If now the machine is moved until finger 83- registers with line a then the drill will'be inposition to drill the rail at b; the fingers 83 and 84: being spaced according to the spacing of a and I). Where only one index finger isused as shown at the opposite end of the machine onrod81 then the top of the rail is chalkmarked at a and b as indicated inFig. 7 and the finger 8-8 is reg-r isteredsuccessively with each of thesemarks; The chalk marks on the rail are, of course, located with reference to. the position of the drilling from the; end-0f the rail. 7

Having. thus described my invention, I claim: i

1. In artrackdrilling machine of the type having a, frame positioned above the track rail and extending a substantial distance upon bothsides thereof and means for supporting the frame on the top of the track rail and an adjustable abutment secured to the frame and having two'positions one t0 bear on the track railand theother to bear on a splice-bar onone side of the track rail, the combination of a. member bearable on the track; rail on a splice-bar on the other side of the track rail, a pivot pin supported by saidv frame upon, which said member is mountech a spring controlled latch forpreventing movement of saidmember from its said twobearing positions, a manually operable member fon withdrawing said latch, a lever for. moving saidmember into either of its bearing positions wherein it-is re stra-inedgby saidlatch and a spring for mov ing said member outof its bearing positions upon a manual operation of said latch.
